Note: I hate netsol. I should move.
==============================
Okay, I want to switch my domain to name servers ns1 and 2.spurvus.com. Currently they are .voxtreme.com. But I am confused. Do I just go into the domain record and enter them, or do I have to "create a Host (name server)"?

If I just have to go to the domain record, okay good fine. But if I have to "create a Host (name server)", what do I enter in the confusing fields it gives me? It asks for:

Host NIC Handle
Host Name
IP Address

It says it will create a host NIC handle for me, but they have incredibly confusing explanations for what exactly host name and ip address are.

IT'S CONFUSING. What do I do?

Well, have you created ns1 and 2.spurvus.com at netsol yet? If not then yes, you'd have to "create a Host (name server)" and all that goes with it.

If it will craete the nic handle, then it needs you to enter Host Name & IP Address:

ns1.spurvus.com
<IP>
ns2.spurvus.com
<IP>

Separately, once for each nameserver you are adding. yes, it is more confusing than everywhere else.
